You’d be better off using Pan Crop, which will work with the original resolution of the pics.
If you set project properties to widescreen, you can then open pan crop, right click on the image and select “Match Output aspect”. This will give you the widescreen aspect, and you may need to move the frame up or down to select the best view. (There is a tool at the left which will restrict movment to up/down only.)
Now, Ctrl C that second event to copy to clipboard. Assuming all the other clips are there on the same track, select the next event, right click and select “Select Events to end”. Now, right click again on the second event and choose “Paste event attributes”.
This will apply the same widescreen crop to all the other pics, and all you need to do is go through and adjust the cropped frame to where you want it.
